BALANCING DEVICE FOR CULTIVATORS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 726,150, dated April 21, 1903.

Application filed October 1, 1902'.

To t/ Z whom if; may concern.-

j Be it known that I, FRANCES M. DWIGHT, a citizen of theUnited States, residing at Willowpoint, in the county of Wise andState of Texas, haveinventedf new and useful Im# provements in Balancing Devices for Culti-v vators orV the Like-to wit, instantaneous ad-f justable seat and tongue-balance-of which' the following is a specification.

This invention relates to a balancing device for cultivators and the like; and the object of the same is to provide a simple 'and effective means for changing the position ofV a driver or operator riding on the cnltivator, so that his weightmay be imposed at different points to regulate the depth of the down-- ward drawing action of the'cultivating-plows or analogous implements into the ground and so counterbalance the machine that .the draftstrain falling upon .the draft-animals under such downward drawing action will be materially relieved and the cultivating-plows or like implements caused to penetrate the ground more evenly.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and. claimed. 4 f

In the drawings, Figure 1 is a side eleva` tion of a portion of a cultivator embodyingv the features of the invention. Fig. is av longitudinal vertical section through a part of a cultivator and the improved attachment. Fig. 3 is a detail perspective View of a movable seat-support, showing the means with which it engages in dotted lines.

Similar numerals of reference are employed to indicate correspondingpart'siu the several views. i

The numeral 1 designates the frame .offa cultivator of anyjpreferred form fh'avingan" arched axle 2, with carrying or ground wheels 3 thereon. Beneath the-frame land extendhaving suitable cultivators,rsuch as shovels or other implements 5, secured in the vusual manner to their rear ends. The beams 4: at the front connect withl aniupwardly-projecting hanger-arm 6, pivotallyattached to the under portion of the frame at a suitable point in advance of the axle 2, and having a depending projection 7 with apertures 8 thereseria No. 125,543. m0 modelo in, which are adjustably engaged by links 9,

running forwardly` to a draft-hanger 10, to which singletrees 11 or the like, are adapted to be adjustablysecured to regulate thedraft, as be readily understood. Connected to thebeams t is an adjusting-chain 12, at-

tached to aniadjusting-lever 13, cooperating -in relation tov a toothed segment 14 on the frame 1. y

rljhe machine as thus far described is one wellknown in v the art and is illustrated to show the practical application of the invention, as it will'be understood that any form Yof cultivator or otherV device may have the improved lbalancing means attached thereto. The improved attachment comprises a rearwardly-projecting looped extensionl, hav- 'ing opposite side members 16 in parallel relation with their forward extremities secured firmly to the bottom of the rear Vend of the frame 1. OnIthis extension 15 a seat-support k.17 is movably mounted, and consists of a boxlike frame open at the bottom and rear end and lclosed at the sides and top. Extending transof usual form is secured on the support 17,

and attached to the front ro1ler'22 is the rear end of a link 24, having its forward extremity loosely connected to the depending member ofY a bell-crank adjusting-lever 25, piv- 1otally 'attached to o ne side of a'ftoothed segment 26, secured on one of the" members 16 lclose to the rear end of the-frame 1, as clearly vshown by Fig. 1. @lever 25 has a spring-actuated dog 27 to cop- The bell-'crank adjustingerate with' thetoothed segment-26m maintain the'adjustment of the seat=support 17 l andseat 23,fcarriedfthereby. ing under the axle 42 areoultivator-beams 4, Y

When the operator or driver ascertains that the shovels, plows, or other-implements on the beams 4t are drawing downwardly" too great a depth, and thereby imposing upon the draft-animals an extralstrain, he shift'szthe lever 25 so as to move thesupport 17A' rear-- wardly on the extension 15, and this adjustment will be pursued until the said downwardly-drawing tendency of the cultivating IOG devices carried by the beams 4 has been counterbalanced and the strain relieved from the draft-animal. This adjustment will also cause the shovels or other implements carried by the beams 4 to penetrate the ground evenly, and if it is found that the penetration is too shallow thesupport 17, together with the seat 23, carried thereby, can be moved toward the end of the frame l a proportionate distance until the defect has been overcome.

The improved attachment will be found exceptionally useful, and the proportions, dimensions, and minordetails may be varied to compensate for the application of the improvement to dierent styles of machines.

Having thus fully described the invention, what is claimed as new is- 1. The combination with a cultivating-machine, of an extension extending rearwardly from the frame thereof, a seat-support slidably mounted on the said extension and cal'- rying aseat, and adjusting means secured to the front portion of said support whereby the Weight of a driver may be utilized to counterbalance other parts of the machine.

2. The combination with a cultivator, of a rearwardly-projecting looped extension secured thereto, a box -like support having rollers therein engaging the opposite members of the extension and carrying a seat on the upper side thereof, and adjusting means mounted on the extension and secured to the front extremity of the support.

3. The combination with a cultivator, of an extension projecting rearwardly from the frame thereof, a box -like support having rollers to engage the said frame, and also carrying a seat, and means for adjusting said support.

In testimony whereof I afiix my signature in presence of two witnesses.
